"Eat Yourself" is a song by Goldfrapp, an English electronic music duo. The lyrics of the song may be open to interpretation, but they seem to touch upon themes of self-destruction, self-love, and the consequences of one's actions. The phrase "Eat Yourself" can be seen as a metaphor for self-destructive behavior. It suggests that if you don't take care of yourself or address your own issues, the pain and negativity that arise from that neglect will consume you. The line "No doubt the pain will instead" implies that if you don't confront your problems, they will manifest themselves in other ways and cause even more pain. The lyrics also mention someone who went south on a train, wearing plastic boots for rain. This can be seen as a metaphorical journey, where someone is trying to escape their problems or find a solution. The fatigue and exhaustion mentioned suggest that this journey is not easy, but rather mentally and emotionally draining. The line "Who will I be when I'm with you again/Silver jet in the sky/You are the pain" might refer to the idea of being in a toxic or unhealthy relationship. It implies that when the person is with someone else, they lose their sense of self and become someone they don't recognize. The silver jet in the sky can be a symbol of escape or freedom, contrasting with the pain that personifies the relationship. Overall, the song seems to explore the complex dynamics of self-love, love from others, and the struggle to find one's true identity amidst these relationships. The lyrics encourage the listener to address their own issues, take care of themselves, and find their own voice ("Got a song, got to sing"). It emphasizes the importance of self-awareness and making choices that lead to a healthier, more fulfilling life.
